Description

Obsidian Specimen, also known as volcanic glass, forms from lava that cools almost immediately upon eruption.

  • Volcanic glass formed through nearly instantaneous quenching of lava
  • Correlates well to Next Generation Science Standards Evidence Statements
  • Obsidian shares many physical properties with its major chemical component, quartz, despite looking dissimilar
  • Despite being dark in color, obsidian is made up of microcrystalline quartz, demonstrated by sharing hardness and conchoidal fracture often exhibited by quartz
  • For use in classroom identification labs and exercises
